Standard Beam Layups


The purpose of this section is to provide information relating to beam selection and to help avoid some common errors made in the usage of glulam products.

Most glulam beams are manufactured using one of three types of layups:

Balanced – V8

  • For applications that have cantilevers or are multi span applications (supported by columns or walls anywhere in mid-span).
  • V4 and V8 BEAMS are surfaced on three sides, top stamped, with two bottom edges eased.

Unbalanced – V4

  • For simple span members supported only on the ends with no cantilevers.
  • V4 and V8 BEAMS are surfaced on three sides, top stamped, with two bottom edges eased.
  • Inverting a V4 Beam Reduces the Bending Design Value by 25%

Columns – Combination 2 or V8

  • Combination 2 for use as vertical columns only.
  • COLUMNS are surfaced on four sides with all edges eased.
